SPECIFICATION forming part of Letters Patent No. 686,823, dated November19, 1901.

Application tiled April 27, 1901.

To @ZZ whom it may concern:

Be it known that I, JAMES MACPHAIL, a citizen of the United States,residing at Blue Island, in the county of Cook and State of Illinois,have invented a new and useful Means for Attaching Spokes, Reel-Arms,Spider- Arms, or the Like to Hubs, of which the following is aspecification.

This invention relates to means for attach- Io ing spokes, reel-arms,spider-arms, and the like to hubs.

The object of the invention is to provide means which are simple,efficient, and economical in construction for attaching spokes,

x5 reel-arms, spider-arms, and the like to hubs.

The invention consists, substantially, in the construction, combination,location, and arrangement, all as will be more fully hereinafter setforth, as shown in the accompanying zo drawings, and finally pointed outin the appended claims.

Referring to the accompanying drawings, and to the various Views andreference-signs appearing thereon, Figure 1 is a View in side elevationof a hub, showing one construction of means for attaching spokes,reel-arms, spider-arms, and the like thereto in accordance with theprinciples of my invention, the arms or spokes being broken off. Fig. 2is a View 3o in transverse section on the line 2 2, Fig. 1, looking inthe direction of the arrows. Fig. 3 is a similar view on the line 3 3 ofFig. 1 looking in the direction of the arrows. Fig. 4 is a detachedbroken view in perspective of a hub end of a spoke or arm adapted forattachment to a hub in the manner shown in Figs. l, 2, and 3. Fig. 5 isa view similar to Fig. 1, showing a modified arrangement of aconstruction embodying the principles of my 4o invention. Fig. 6 is adetail view in section on the line 5 5 of Fig. 5 looking in thedirection of the arrows. Fig. 7 is asimilar view on the line 6 6, Fig.5, looking in the direction of the arrows. Fig. 8 is a View similar toFig. 2 on the line 7 7, Fig. 5, looking in the direction of the arrows.Fig. 9 is a view similar to Figs. 2 and 8, showing a slightly-modiedarrangement of locking-tongue. Fig. 10 is a detail view in section onthe line 9 9, Fig.

vor any well-known manner.

The same part is designated by the same reference-sign wherever itoccurs throughout the several views.

In the drawings reference-sign Adesignates a hul), which may be of theusual 0r any wellknown construction and arranged and mount- 6o ed upon ashaft, rod, or axle B in the usual These parts being of the usual or anywell-known construction or arrangement require no speci-al descriptionherein.

In carrying out my invention I propose to provide means whereby thespokes, reelarms, spider-arms, or the like may be quickly applied orattached to the hub in a manner permitting of the removal thereof forrepair 7o when necessary and wherein such arms or spokes are efficientlylocked in attaching relation with respect to the hub. These resultsmaybe accomplished in many specifically different ways. In the drawings Ihave shown several diierent ways in which the desired objects may beaccomplished; but I desire it to be understood that my invention is notto be limited to the exact details of construction shown, as many otherarrangements for 8o 4 I mount a plate C upon the face of-the hub 85 Aand provide said plate with radiating extensions I), having side iiangesE, bent up to form channels or recesses. In practice I preter to forlnsaid plate Cof sheet metal and to slightly incline the upturned edges Eof the 9o extensions D thereof toward each other to form dovetailedchannels, as most clearly shown in Fig. 3. As many of such channeledextensions may he provided as may be desirable to accommodate therequired number of spokes or arms to be attached to the hub. With thisform of fastening I employ a spoke, reel-arm, spider-arm, or the like(indicated at F) of channel shape in cross-section, as most clearlyshown in Fig. 4, and also of sheet metal and with the side portions orflanges G thereof placed a distance apart normally to correspondsubstantially to the transverse Width of lthe space between the flangesE of the channeled extensions D. From this description it will beunderstood that when the inner ends of the reel-arms or the like aretelescoped or inserted endwise into the channeled sections a slightcontraction or compression is exerted by the dovetailed crosssectionalshape of the channeled extensions upon the edges or side ilan ges G ofthe spokes or arms, tending to compress the same toward each other, asclearly illustrated in somewhat exaggerated condition in Figs. 1, 2, and3.

Adjacent to the inner ends of the spokes, reel-arms, or the like theflanges G are kerfed or split transversely, as clearly shown at H, (seeFigs. 2 and 4,) thus forming spring lips or portions .I at the extremeinner ends thereof, which when said inner ends of the spokes,

arms, or the like are inserted a sufficient distance into, through, orupon the extensions D are thereby relieved of the compressing strainexerted upon the flanges Gr by the inner Walls of the flanges E of saidextensions, and hence are permitted to spring outwardly by their ownresiliency and engage behind the inner ends of flanges E, as clearlyshown in Fig. l, thereby forming an automatic springlock, preventing theWithdrawal of the spokes or arms without again forcibly compressing thespring lips or portions J sufficiently to enable the same to clear theend of the channeled section. By this construction it Will be seen thatIprovide an exceedingly simple arrangement inexpensive in manufacture`for attaching the spokes, spider-arms, reel-arms, or the like to thehub. It will also be seen that said spokes,arms,or the like areautomatically locked in attached relation to the hub, but may bewithdrawn therefrom for replacement or repair. It will also be seen thatI am enabled to employ channeled spokes or arms struck or bent up out ofsheet metal, thereby securing lightness, simplicity, and economy inconstruction Without sacriicing anything of strength or rigidity.

It may sometimes be desirable to employ tubular-shaped spokes or arms.My invention, therefore, also includes the application of the principlesabove set forth to spokes or arms which are tubular or cylindrical incrosssection. Thus in Fig. 5 I have shown the plate() provided Withtubular or cylindrical extensions D', to which tubular or cylindricalshaped spokes or arms F are attached. In order to form the automaticspring-lock for locking the tubular or cylindrical spokes, arms, or thelike to the hub-plate, the extensions D and the spokes, arms, or thelike F are provided with engaging spring-tongues and shoulders. It isobvious that the en gaging shoulder may be formed on either theextension or the spoke or arm, and the coperating spring -lip may beformed on the other of said parts. In the particular form shown,however, (see Figs. 5, 6, and 7,) the extensions D' are provided withopenings K, and spring-tonguesL are stamped or punched out of the spoke,arm, or the like, whereby when said spoke, arm, or the likeandextensions are inserted the one Within or upon the other saidspring-lip will engage automatically behind the shoulder formed by theslot or opening K, thereby forming a lock for locking the spoke or armto the extension.

The spoke, spider, reel-arm, or the like may be telescoped into theextension of the hubplate, as shown in Fig. l, or be telescoped upon theextension, as shown in Figs. 5 and 8.y In Fig. 9 I have shown aconstruction wherein a tubular form F2 of spoke or arm is employed andis telescoped into a tubular extension D2 of the hub-plate C2, the spokeor arm being transversely kerfed or slit for a portion of thecircumference thereof, as indicated at M, to form spring-lips N, (seeFigs. 9 and 12,) Which When the ends of the spokes, arms, or the likeare telescoped into the extensions D2 spring out behind the inner endsof extensions D2 in the same manner as above described, thereby formingan automatic spring-lock therefor. In the tubular form of spokes, reelor spider arms, or the like it is obvious that any particulararrangement of tubes may be employed. For economy of construction andfor 'facilitating the attachment of said spokes or arms to the hubasplit tubular construction such as is shown may be employed, it beingunderstood that Where the tube is to be telescoped upon the extension ofthe hub-plate the normal internal diameter of the tube should beslightly less than the external diameter of the extension, so as tosecure the desired resiliency to enable the spring-lip portion to snapinto place behind the shoulder or end of the extension. to be telescopedinto an extension the normal transverse area of said spoke or arm shouldbe slightly greater than the transverse area of the extension for thesaine purpose. This is true Whether the spoke or arm is of cylindricalor of any other transverse or cross-sectional area, and it is obviousthat any desired cross-sectional shape or area of spoke or arm and hubextension may be employed without departure from the spirit or scope ofmy invention. It is also obvious that any desired construction of hub orhub-plate or hub or hub-plate extension may be employed and any suitablematerial may be employed in constructing or forming the hub or hubextensions or spokes or arms, but sheet metal forms a most convenient,simple, and economical material by reason of its natural resiliency andadaptability of being Worked up into the desired shape.

While I have described my invention as applicable for attaching spokes,reel-arms, and spider-arms to hubs, it is obvious that the Similarlywhen the spoke or arm is.
